Voltage source and terminal voltage can be related as
Right Answer is:
Terminal voltage is always lower than source emf
SOLUTION
A practical voltage source like a battery has drooping load characteristics due to some internal resistance. A voltage source has small internal resistance in series while a current source has some high internal resistance in parallel. In practical voltage sources, the voltage does not remain constant but falls slightly. Therefore the terminal voltage is always lower than source EMF.
